BUTTON.

SPECIFICATION forming part of Letters Patent No. 352,270, dated November9, 1886.

Application filed January 27, 1885. Serial No. 154.152. (No model.)

To all whom it may concern: 4

Be it known that I, ll/IADISON D. SHIPMAN, a citizen of the UnitedStates of America, residing at De Kalb, in the county of De Kalb andState of Illinois, haveinvented certain new and useful Improvements inButtons, of

groove or recess in the stud; and the invention consists in the peculiararrangement and construction and combinations of parts hereinafter moreparticularly described and claimed.

The accompanying drawings show my improvement on an enlarged scale, thebetter to show the parts.

In said drawings, Figure 1 isa vertical central section of my button inposition for use. Fig. 2 is a reversed plan of the cap of the button andits tube. Fig. 3 is a vertical section of the same before itsattachment. Fig. 4 is a section of the stud before its attachment. Fig.5 is a section of an eyelet used for fastening the stud. Fig- 6 is asection of a washer for fastening the button. Fig. 7 is a modificationof the mode of fastening the stud.

A represents the cap which forms substan tially the top of the buttonproper, and isprovided with a central tube, B, said cap and tube beingstruck up in one piece, and preferably having the tube formed thickestnear its junction with the cap at the point where a round aperture or aslot, 0, is formed, through which passes one end of a spring, D, coiledroundinside the cap,which end catches into an annular groove in astud,E. At F is shown a J shows an eyelet which is Having thus describedall the parts, I will now proceed to describe the mode of uniting thesame to the material. I

In securing the stud a holeis made through the material in the usualmanner,and at'tenthe I stud E is passed through it the eyelet Jisslipped over the shank of the stud, and is then pressed down by asuitable punch or other device,and

'when the lower part of the eyelet strikes the enlargement I it isforced open and spreads, as shown in Fig. 1, until it extends outwardunder the rim h, which by the pressure of the punch is flattened downupon the lower part of the eyelet, and thus the stud is securelyfastened in place.

To secure the button top A the tube B is passed through a hole in thematerial, and a washer, if one is used, is placed on the lower end ofthe same, when the force of a punch or other suitable instrument willclinch the lower part ofthe tube and spread it, as shown, and firmlysecure the button top or cap to the material.

When in use,it is only necessary to press the button down over the stud,when the latter will enter the tube, and its point will push back theend of the spring D, which, when it reacts, will enter the annulargroove in the stud, and thus the button and stud 'will be securelyfastened together against) any ordinary strain. A sudden pull, however,in the proper direction will easily separate the button from the stud,and thus the glove or other object to which the stud and button areattached may be fastened or unfastened with the greatest ease. I

Instead of making. the stud, base, and the rim all in one piece, asshown in Figs. 1 and 4, the stud may have a base of comparatively smalldiameter, and a cap, L, (see Fig. 7,) with an overturned flange or rimformed on its periphery, and the whole may be united by pressingon theeyelet, as shown in said Fig. 7

It is of course obvious that the studs may be made solid or hollow,asdesired; but Iprefer them made hollow, as shown in Figs. 1 and 4, andwhere I refer to studs in the following claims I meanto include solid'aswell as holwhich together constitute a whole piece in which one portion,as the cap A, is to be secured to the fabric or material,while the otherportion, as the tube B, serves as a connected and ready means forclinching the first-named portion to the material.

When the cap and tube are made separately, as has been proposed, and thestud is pushed into the tube, there is a tendency to displace thetube,and unless it is very strongly fastened below, it will in course oftime be- I come loosened and be forced upward, and thus be made useless.This will not occur with mine, and, moreover,with my construction thecap and tube may be used as a shirtstud without being fastened to thecloth by leaving off the fastening-washers and simply using the partsshown in Figs. 3 and 4. If the corre sponding parts in those buttonshaving the cap and tube made separately were used in this way, said capand tube would separate, and

the button thus become useless. The other advantageous results obtainedare, that the cost of producing the single pieces A B will be very muchless than that of separate caps and tubes, and the work and expense ofassembling the separate pieces are wholly obviated, which is of greatimportance; and, further, themaking of the button-top proper and tube tocompose outward the base of the eyelet under spurs,

which the point of the spring catches,substanwhich spurs are obviouslythe equivalent of the flange h shown in this application, when used inconnection with the enlargement and 5 eyelet before referred to, and ascovered in claim 4 in this specification.

\Vhat I claim as new is- 1. In a separable button,the hollow cap andtube A B,formed integral,the hollow cap portion being the button-topproper, and the tube portion being the means for uniting the connectedbutton-top with the fabric or a piece on the fabric byclinching,substantially as and e for the purpose set forth.

2. As an improved article of manufacture, aseparablebntton consisting ofa hollow cap anda tube both formed in one piece, a spring having itspoint projecting through the tube, the cap being adapted to receive andhold the spring and the tube having a hole to receive the point of thesame, and a slip-stud provided with an annular groove or notch, intotially as described.

3. In a separable button, a tube perforated at its side to receive thespring and made of increased thickness around the tube near theperforation, substantially as and for the purpose specified. 7o

4. A stud having a base provided with an inwardly-turned flange and anenlargement near the junction of the stud and base, constructed todeflect the fastening-eyelet toward the flange and under the same,substantially as described. In testimony whereof I aflix my signature inpresence of two witnesses this 24th day of January, 1885.
